Botany on a plate. Pleasure and the power of pictures in promoting early nineteenth-century scientific knowledge

In early nineteenth-century Britain the use of pictures in introducing novices to the study of science was contentious, leading to debates over the ways in which words and images constituted knowledge and over the role of pleasure in intellectual pursuits. While recent studies have stressed visual representation as a critical element of science and considered its relation to the written word in conveying information, this essay explores the nineteenth-century preoccupation with the mind and mental faculties in relation to corporeal responses to explain concerns over the role of images and the process of recognition. By considering illustration in this way, it argues that popular botany was defined by many expert naturalists as the means by which private individuals could best be encouraged to extend their aesthetic appreciation and love of plants to an active and participatory pursuit of science.

Can social support buffer the association between depression and suicidal ideation in adolescent boys and girls?

The purpose of the current study is to investigate social support (from parents, classmates, teachers, and close friends) as a protective factor in the association between depression and suicidal ideation. Data on students’ levels of social support, depression, and suicidal ideation were collected from 399 9th‐grade students using the Child and Adolescent Social Support Scale (CASSS), the Children's Depression Inventory, 2nd Edition Short Version (CDI 2), and the Suicidal Ideation Questionnaire ‐ Junior Version (SIQ‐JR). Results of hierarchical linear regressions indicated parent, classmate, and close friend social support buffered the association between depression and suicidal ideation. Close friend social support as a buffer appeared to be more robust for girls. Implications concerning these findings are discussed.
